Letters Patent N 101,574, dated/1PM! 5, 1870.

IMPROLVEMENT IN SULKY FLOWS.

The Schedule referred to in these Letters Patent and making part of the same.

To all lwhom it may concern:

Be it known that I, JOHN G. BOYD, of l)ecatnr,

` in the county of Wise and State of Texas, have invented certain new and useful Improvements in Sulky Plows; and I do hereby declare that the follow- .ing is a full and exact description thereoreference being had to the accompanying drawings making a part of this application.l

The object of .my invention is to provide an economical and certain means for regulating the depth of furrow, and consists in hanging the beam as willbe hereinafter Vmore fully set forth.

To enable those skilled to makeaud use my improved sulky plow, I will proceed to describe the construction and operation of the. same, referring by letters to the accompanying drawings.' l

Figure 1 is a top view;

Figure 2, a side view; and

Figure 3, afront view on a reduced scale. Similar letters of reference denote like parts in the several views.

A A are the two wheels, and

B,`the` axle ofthe sulky, the former secured in the usual manner by pins a.

At equal distances from the wheels are erected, upon the axle, two uprights'Q C, to which is secured the drivers seat I), the standards shouldered at the u`pper side of .the axle, and their lower ends protruding a short distance below the axle, to serve as guides for the beam, as will be presently explained.

E is the beam, provided, near to either end, with tongues F F', the front end being also furnished with a 'clevis, G, and staples b b.

The tongues are provided with any desired number of holes, for the purpose presently explained, the standards C C being. furnished in a like manner with holes for the reception of a pin, d.

The axle, on its under side, is recessed or cut away 'to form a seat for the beam E, which is secured to the sulky and held in -place by means of a lever-bar, H, passing between the two uprights, to which it is secured by the pin d. The tongues F F' of the beam passing up through slots formed at either end of the lever-bar, are secured to the same by pins or bolts.

The plow-shares are scoured to the beam by means movement'of the beam, which is raised and lowered v iu parallel lines in the following manner, to wit:

The pin K, being withdrawn from the tongue F, the rear end of the lever-bar is elevated, which lifts the sulky in a perfect-ly vertical line a distance equal to the distance traveled by the lever,`or, in other words, drives the plowpoints into the ground. The pin K is then putfthrough the hole in the tongue F immediately under the lever, which holds it in place, aud,consequcntly, the furrow made will be of uniform depth.

Lhe protruding portions of the uprights serve as guides to the beam and prevent any lateral movement.

The object of the series of holes in the uprights and the tongue F will readily be understood to be for the purpose of regulating the `extent of the movement of the beam by the lever-bar` It will thus be seen that the depth of furrow having been determined upon, the beam is set accordingly, and the driver takes his seat and is relieved of all the skill and labor necessary in'making a furrowmf uniform depth. g

I have discovered, by practice, 'that square corners are easily turned with my improved plow, and all work required to be done by it readily and easily accomplished. Of course the number of furrows may be increased. vby slight modifications in the design,

, without departing from the spirit of my invention.

Having thus described the construction and operationy of my improved plow,

What I claim as new, and desire to secure by Letters Patent, is-

The lever H, fulcrunied at (l, the standards F and F', beam E, and guides O, all arranged 'and operating substantially as and for the purposes set forth.

In testimony whereof I have hereunto set my hand and seal this 4th day of November, 1869.
